Abstract

U ovom diplomskom radu prikazan je razvoj 3 – osne numerički upravljane glodalice.
Predmetna glodalica predviđena je za obradu aluminija i aluminijskih legura, drva te u rjeđim
slučajevima i tvrđih materijala. Jedan od najbitnijih dijelova alatnog stroja, a time i glodalice je
temeljna ploča. Temeljna ploča stroja bit će izvedena kao sklop aluminijskog okvira i
polimernog betona (epoksi granita). Aluminijski okvir se postavlja u kalup nakon čega se u
kalup ulijeva polimerni beton. Kako bi se pojednostavnilo lijevanje, stroj je segmentiran u dvije
cjeline temeljnih ploča, postolje i most. Za svaku temeljnu ploču razvijen je zasebni oblik
kalupa. Kalup je izrađen od sjajno lakiranih medijapan ploča (drvenih ploča) koje se režu i
spajaju u željeni oblik. U drugom koraku provodi se proračun standardnih (kupovnih)
elemenata kao što su: motorvreteno, posmični motori, kuglično vreteno, uležištenja i linearne
vodilice. Što se tiče upravljanja i regulacije stroja dano je idejno rješenje. Razvoj cjelokupnog
stroja sa svim potrebnim dijelovima prikazan je u programu Catia V5R20. Tehnička
dokumentacija i slike razvijenog stroja nalaze se u prilogu ovog rada.

Abstract (english)

This thesis presents the development of a 3-axis CNC milling machine. This Machine is to be
used for milling of aluminum and aluminum alloys, wood and even a hard metal. One of the
most important parts of the CNC is the base. The machine base will be made of aluminum
substructure and polymer concrete, in this case epoxy granite. Substructure is placed inside of
the mould and covered with polymer concrete. For easier assembly, the machine base is
separated in two parts: pedestal and bridge. For both parts new and separate molds are
constructed. Mould is made of highly varnished medium density fibreboard (MDF) panels
which need to be cut and connected into the wanted shape. Second step of development is to
list and calculate estimated price of all parts needed for this CNC milling machine, which are:
motor spindles, shear motors, ball spindles, bearings and linear guides. As for the control system
of the machine, a preliminary solution is given. The development of the complete machine with
all the necessary parts is shown in Catia V5R20 software. Technical documentation and pictures
are attached at the end of the thesis
